it's already defined in include files -> #define HUGE_VAL _huge_dble in math.h ... but any use of this definition don't work

   data.u = X * DEG_TO_RAD;
   data.v = Y * DEG_TO_RAD;
   data = pj_fwd (data, ProjInitRef);
   //if (data.u != HUGE_VAL) <- don't work...

   if (data.u > 1.0e-100 || data.u < -1.0e-100)    //<-instead of huge_val
